Description

Meitoda ¾ Artificial nail composition Conventional technology

Conventionally, artificial / Ma compound is prescribed on nails? There was an artificial nail that was made to be hardened by irradiating ultraviolet rays after applying it to ^.

However, since the conventional artificial nail composition is an ultraviolet curing type, it has been difficult to add an arbitrary flavor. That is, in general, fragrances have phototoxicity and photosensitization, and when phototoxicity and photosensitization fragrances are activated by ultraviolet rays, skin isflammable and pigment is deposited on the skin. This is because there are cases where

In general, in cosmetics, a method of drastically reducing the amount of added fragrance is employed to avoid problems of phototoxicity and photosensitization. If the amount of addition is small, it is difficult to maintain the emission of a pleasant scent from the obtained artificial nail for a long period of time.

Therefore, there is a demand for an artificial nail composition to which an arbitrary amount of an arbitrary fragrance can be added without considering the problems of phototoxicity and photosensitization. As a result of repeated studies to solve the above problems, the present inventor is an artificial nail composition containing a monomer, a polymerization initiator, and a solvent, in which a fragrance is contained, and a pigment is also contained depending on the composition. It was found that the above-mentioned task can be solved by using an artificial nail composition that specializes in this.

Example 2

Lavender oil (200 ml) was used as a fragrance, and phthalocyanine blue (100) was used as a pigment. Other raw material ratios, mixing methods, and other production methods were the same as in Example 1 to prepare an artificial product. When the artificial nail composition prepared as described above was used by 50 women who frequently use artificial nails, there were no abnormalities in the skin or nails. In addition, when the feeling of use was determined, compared to conventional artificial nails, there was no unpleasant odor during artificial nail formation, and on the contrary, a pleasant fragrance was enjoyed. Most of the impressions that fashionability has improved were very popular. The invention's effect
